CONTROLLING MECHANISM FOR BALLNG MACHINES.

Application filed February 5, 1918. Serial No; 215,495.

To all whom t may concern: l

Be it known thatk 1,- Ma'rrnas il. KAsrAnr, a citizen of the UnitedStates, residing at Chicago, inthe county of Cook and State oi illinois,have invented` certain new and uset'ul improvement-s in ControllingMechanism for Balling Machines, or' which the following is a full,clear, and exact specification. i

This invention relates to balling machines and more particularly-tocontrolling mechanism for balling machines and to the tension devicesemployed in connection with said machines.

The object of the invention is to provide meansl for automatically andmanually conf trolling the operation of machines of the class described,and to provide means for so tensioning the guiding and polishing memberthat a uniform and adequate degree` of tension will be obtained at alltimes.

lith the above objects in view the invention consists, briefly, in atwine guiding member, actuating means for the guiding member and aplurality of controlling meansr for the actuating means, comprisingmanuallyand automatically operable controllingk means, the manuallyoperable means being operable 'from the front or from the rear of themachine and the automatically operable controlling means `beingthrowninto operation when the passage of the thread or twine tl'irough themachine is interrupted.

rllhe twine guiding and polishing member is provided with tensioningmechanism such as gravity actuated means for holding` theI deviceagainst the ball being wound, yand additional means, such as africtionbrake, is provided to assist the tensioning mechanism in maintaining auniform and constant tension and to prevent sudden release or snappingback of the tensioning mechanism.

I have illustrated one embodiment of my invention in the accompanyingdrawings, and in these drawings,-

toward Figs. 7 to 13 inclusive are detail viewson an enlarged scaleillustrating the construction of the automatic stopping mechanism whichcontrols theoperation ot' the machinek when the thread breaks orwhen the,ballI is completed; y

i F ig. 14@ is' a front elevation on an enlarged scale ot the twineguiding and ballpolishing mechanism, and t Fig. 15 is a sectionalviewillustrating the reciprocatory feeding mechanism for the twineguiding member. l

The trame 2O of themachine is of the usual `construction having a front'upright portion 21 and a horizontal rear portion 22. rihe portion 22supports an upright supporting standard 23 which vin turnv carries a`supply reel 24tand the associated parts. The supply rcel 24 comprisesradial arms 25 car-- ried by a sleeve which in turn -is rotatablycarried ona shaft 26 mounted inbearings on the standard 23. rhe sleevewhich carries the radiatingreel armshas secured thereto at one end anotched disk 27 which cooperates with a lever 28 in such a manner that apin 29 carried by the lever is adapted to rest in one of the notches' ofthe disk and thereby secure the reel aga-inst rotation.

The tensioning device for the supply bobbins comprises a plurality .ofV-shaped plates 30 p'ivotedto an arm 31 which in turn is secured to asleeve 32 journaled on a shaft carried by the standard 23'. This sleeve32 carries at one end a triangular plate 33 provided on one ot its sideswith a iiat bearing portion or track 34, and the sleeve 32 has securedat its opposite end a grooved disk A chain 3G is secured to the disk 35and is connectedat itsV opposite end'to a vertical link 37 which in turnis connected'y at its lower end by a pin and slot connection withlalever 38 pivotedv at 39 to the frameot the machine. The lever 38 isconnected at its opposite end by a pin andslot connection with a tootlever 40, and by pressingvon the At'ront endo'l' this toot lever theoperatorA when starting t-he machine can rotate the disk `35, sleeve32,` arm 31, and thereby litt the tension devices 30 from contact kwiththe supply bobbin. The track 34 yon thel plate 33 carries a pin 41secured against displacement by means of suitable flanges, and this y vpin 4-1 is secured to a downwardly extending` rod 42 which carries atits lower end a weight 43f It desired, the pin-41 may be provided withan anti-friction rollerito*fa-p` n stop the machine.

cilitate its sliding movement on track 34. The weight rests on a spring44 which is secured against removal by means oil a nut 45. The Weight 43acting through the rod 42, pin 4l, track 34 and plate 33, increases the`tension on the ball as illustrated in Fig. 3.

The tensioning device above described is that of the patent to G, L.Rue, No. 1,385,925, July 2G, 1921 and forms no part of my invention andhas been shown merely incidentally, and it should be understood that anyother suitable form of tensioningmechanism may be employed in thismachine.

The balling mac ine proper comprises automatic stop mechanism which isactuated when the thread breaks or when the supply bobbin runs out,manually operable stop mechanism which may be actuated from either thefront or rear of the machine, and twine guiding and `ball polishingmechanism, and the driving meanstherefor. Means are also provided forsecuring the proper tension on the twine guiding and ball polishingmechanism.

The automatic stop mechanism will lirst be described. After the twine oryyarn 46 leaves the supply bobbin, it is carried around a rotatablymounted V-shaped shea-ve 47, to a carriage 48 slidably mounted on bars49 carried by the frame of the machine. This carriage 48 is providedwith a sheave 50 and is normally pressed toward the rear of the machineby springs 5l carried by the bars 49. Buffer springs 49 are provided onthe rear portions of rods 49 to cushion the carriage when the twinebreaks and the carriage is pressed rearwardly by springs 5l. From aninspection of Fig. 3 it will be seen that the tension on the thread asit is being drawn ilrom the supply bobbin and over the sheaves 47 and50, normally pulls the carriage 48 toward the front of the machine andagainst the tension of the springs 51, but when the thread or twine isbroken or releases thel springs 51 press the carriage rearwardly on thebars 49and by means of suitable trip controlled mechanism hereinafterdescribed,

This cooperating mechanism will now be described.

The carriage 48 is provided on its upper rear portion with a projection52, which located in the path of, and is adapted to contact with, thelower end 53 of a lever pivoted at 54 to the frame of the machine.kopposite end ot this lever has forwardly projecting substantiallyhorizontal bearing portion 55 which normally contacts with a notchedmember 56 secured to a pintle 57 journaled on the machineJ frame. Thismember 56 is elongated and its inner portion forms a stop for a member58 pivoted to the frame at 59 and bifurcated at its upper end as shownat 60. The upper bifurcated end 60 of the member 58 receives adownwardly The l projecting rib 6l carried by a lever 62 which carriesat its inner end a sleeve G3 pivoted on vertical pivot G4 to the machineframe. Formed integrally with t-he sleeve 63 is an arm G5 which carriesat its opposite end a. link G6 pivoted at 67 to a sleeve 68 which inturn carries a biturcated belt shipping fork 69. The sleeve ('38 isslidably mounted on a rod 7() and is normally pressed by a spring 71 ina direction to ship the belt 72 from the fast tothe loose pulley. Theoperation of this automatic stop mechanism will now be brieflydescribed.

When the thread or twine breaks, the springs 51 press the carriage 48rearwardly on the rods 49, and the upwardly projecting portion 52 of thecarriage contacts with the downwardly proj ectingl portion 53 of alever, the upper end 55 of' which is thereby pressed downwardly, movingthe member 56 on its pivot. llVhen this member 56 is forced downiardlythe pivoted member 58 is free to rotate about its pivot in a clockwisedirection, thereby releasing lever 62 and with it the sleeve G8 and beltshipping fork G9 which are forced by the action of the spring 7l towardthe lett in Fig. l, thereby shipping the belt trom the i'ast to theloose pulley.

The means for shifting this mechanism automatically when the bobbinbeing wound is full, and for manually shifting the belt shipper Lfromeither the frontor the back of the machine,will next be described.

The pintle 57 has fixed to it at its front end a substantiallyvertically disposed lever 73 having at its lower end an adjustable screw.74. The lever 73 is normally forced in a clockwise direction about itspivot by Ineans of a contractible spring 75, one end ot which isconnected to the lower part ot the lever and the other end of which isconnected to the frame. The screw 74 carried by the lower end of thelever 73 is located in the path of the twine guiding and ball polishing`device 7G, pivoted at 77 to the trame of the machine. After this device76 has been forced outwardly a certain distance, by reason of itscontact with the twine on the ball being wound, it will contact with thescrew 74 thereby rotatingthe lever 73, and the pintle 57 and the member56 carried by the opposite end of said pintle. The movement of thispivoted member 5G will have the same` effect as was described above andwill release the pivoted member 58, thereby allowing the clutch shippingfork. under the torce ot the spring 71 to ship the belt from the `fastto the loose pulley.` By means oi the screw 74 on the lower end` of thelever 73. the operator can control the size ot the ball being wound.

The upwardly projecting end of the lever 7 3 extendsin the path of acone 78 carried by the front end of a rod 79 which in turn is providedat its rear end with a handle 80.

This rod 79 is slidably mounted in bearings 81 and 81 carriedrespectively on the frame of the machine and on lever 62, and said rod`carries intermediate the front bearing 81 and the conical end, a spring82 which normally presses the rod toward the front of the machine. lfthe. operator at the rear of the machine pulls on the handle 80, the

` pushing on the cone-shaped end78 of rod 79. To put the machine intooperation, the hand lever 62 is swung forwardly until the memberv 56swings up into the path of the lower end of member 58 which has jmovedbackwardly as lever 62 was beingy moved forwardly, the upward movementof member 56.1ocking lever 62 and the belt shipping mechanism connectedto .it in active position.

The tensioning means for the twine guiding and ball polishing devicewill nextbe described. n

rrs stated above, this guiding device 76 is pivoted at 77 to the frameofthe machine and comprises a lever, the lower end of which carries aquadrantv 83 which meshes with a pinion 84 carried by a pintle Thispintle 85 also carries a disk 86 `around the periphery of which ismountedy a bandL 87 secured at `one end 88 to the machine,-

frame and secured at its opposite end at 89 to a `llever `90 pivoted atV91 to the frame of the machine. rlhis lever 90 carries on `its outerend a weight 92 which exerts a downward force on the band 87, therebyputting a tension on the pinion 84: and through the pinion and quadrant88 on the twine guiding and polishing device 76. rlhere isv also securedto the lower end of this device 76, adjacent the quadrant, a link 93pivoted at its opposite end at 94: to a bell. crank'lever 95 pivoted onthe frame of the machine. The bellcrank lever is pivoted at its oppositeend toa link 96 to which is secured aweight 97.

From the above description it will be seen that the weight 97 tends torotate the upper end of the device7 6 in an anti-clockwise direction oragainst the surface of the ball,

and that the weight 92, acting through the band 87, pinion 84 andquadrant 83, cushions or puts a brake on the tensioning mech! anism andtends to make this tension uni` form and to prevent any sudden change intension.' rihis uniformity of tensionis nec essary kin this typefofmachine since any de-y parture from a constant tension will 1mme-`diately aiiect the winding` of theiball, produce irregularities andoften 'a breakage of the twine. The brake. band 87 and weight 92 alsoresists the outwardinovement of the7 guiding device 7 6, therebyassisting in compacting the ball and permitting the use of a smallerweight 97 than would be otherwise required. the brake yband preventsweight 97 from immediately throwingthe guiding device 76 against thecollapsible spindle, and in this way prevents a possible injury to. thefingers of the operator and to the guiding When the full ball isdoi'liedi eoy device.` The tension device 76 is carried by a bary 98` (see Fig.15), which is reciprocated by meansv of a cam 99 driven by suitablegearing 100, which, in turn, is driven in amanner hereinafter described.ln Fig. 15 is shown also the drive for the collapsible spindle 101-mounted on the front end of shaft 102. rlhis shaft carriesa worin gear103` which is driven by a worm 104C carried' by a shaft 105 upon whichare mounted the driving pulley and loose pulley which are driven` bythebelt 72 above described. 41n llig. 2 l have illustrated the usuallever mechanism for collapsing the spndle rwhen the yball has beenwound, and it is desired totake off the full ball.- yThis mechanismlcomprises afoot treadle 105', pivoted to the machiner frame and carryingan upwardly i projecting link'106 which is pivoted at its upper end to abell crank lever 107. This levery is connected at its opposite end by apin anc slot connection to a slidably mounted rod k108 whichcarries atits frontend a fork-` which projects between the flanges on f a collar109 and reciprocates this collar, thereby collapsing the spindle101 in aman* ner well. known in the art, and not specifically hereinillustrated.

rlrhe operation Iof the various parts of this machine has been describedin connection with the description of the structure and no furtherdescription of the operation is therefore thought to be necessary. f n

From the above description it will be seen that 1 have provided asimple, practical and eflicient balling ymachine having means' forautomatically stopping the machine when rthe thread breaks,for manuallystopping the machine when desired from a position in the front of or inthe rear of the machine, and for tensioning the twine guiding andpolishing device in such a manner that said device will not snap backand injure the hand of the operator when the full ball is doifed.
